摘要

Low-level, inadvertent, pediatric ingestion of lead (Pb) contaminated soil can produce sub-clinical adverse health effects. The problem posed by Pb in soil is that it is relatively abundant in urban-industrial areas with long-duration occupancy (e.g., older inner-city areas). In this context, effective risk reduction requires an appropriate form of mitigation. While many remediation strategies have been advocated and implemented, there is no consensus on what constitutes a "cost-effect" intervention that can be widely used to address a problem that can be very expensive to remediate. Here, we focus on the addition of phosphorus to soil as a way of converting the Pb to a sparingly soluble (less bioaccessible) form.
